urr sf JOHN B. MURRAY, OF NEW' YORK, N. Y.

ENVELOP.

Specificaton of Letters Patent No. 30,980, dated December 18, 1860.

To all 'whom 'it may concern:

Be it known that I, JOHN B. MURRAY, of the city and county of New Yorkand State of New York, have invented certain new and useful Improvementsin Envelops; and I do hereby declare that the following is a full andcorrect description thereof, reference being had to the annexeddrawings, making a part of this specification, and to the letters ofreference thereon.

My said inventon relates to envelops used for the transmission ofprinted circulars by mail. Such circulars are now transmitted at therate of one cent postage in ordinary letter' envelops by leaving` themunsealed for the purpose of inspection by the officials of thePost-Office Department. In order to inspect the circular it must bewithdrawn from the envelop. In consequence of the flap beng loose andunsealed, the circular is liable to escape from the envelop and be lost.

The drawings illustrate my inventon,

F gure 1 being a view of the envelop extended and Fig. 2, a perspectiveView of an en- Velop inclosing a printed circular. Letters A representopenings in either one or both ends of the envelop. The opening` notbeingquite the width of the end of the envelop the circular Will notslip out when the flap is sealed and yet permits full inspection of thecircular or other contents and of withdrawal if desired.

I claim as my inventon as an improvement in envelops:

The openings A in one or both ends of the envelop substantially asdescribed and for the purpose set forth.
